So I got home from work, and starting playing dark souls on my PC. I'd just gotten a new grtaphics card and was trying it out. Anyway it suddenly freezes and the sound goes into a loop. So I turn the PC off.

When I start it again everythign lights up and the fans spin, but, there's no beep. All the other drives sound like they're spinning up fine. I've already tried removing the ram, when I did I got 4 beeps repeating, so it seems like the ram isn't the problem. I've tried shifting the position of the RAM too.

The specs are

Powersupply Corsair 550W
Graphics Card: Geforce GTX 960
Motherboard: M4A77
The processor:amd phenom ii 965 quad core 3.4 ghz (black edition)
8Gb RAM
The operating system is, unfortunately, windows 10

The computer is second hand, but, the power supply is fairly reccent and the graphics card is less than a week old.

I was planning on getting a new motherboard and processor soon, so if either of them are the problem that's not too bad, but is that likely?

Quik follow up, removed he graphics card and swapped it with the old one, while I was doing hat I noiced a lead to the hard drive was loose, so I pushed it in. Computer started up fine.

Justswapped out he graphics cards again to the new one and again it's booting up fine, could i have been the loose cable?

Yes it most certainly could of been, it could have had a intermittent issue whereas it would send some data but lose other bits of data. You should be good to go although just remember to keep an eye out for odd things. What model PSU?
